This research aims to develop a high-efficiency narrowband yellow OLED using a new emitter material.
Utilized an ortho-B-π-B strategy to create a long-wavelength MR-TADF material.
Characterized the emission properties of the developed material, focusing on its molecular vibrations.
The emitter QuBN exhibited yellow emission with a peak at 552 nm and a FWHM of 20 nm.
Achieved an impressive emission efficiency of 91% in the new OLED design.
Abstract
We report an ortho-B-π-B strategy enabling a long-wavelength MR-TADF material with suppressed molecular vibrations. The emitter QuBN shows yellow emission peaking at 552 nm with 20 nm FWHM and 91%...
